PC/104-Plus – COM-1460 Module 33
Firewire
Firewire is a high speed bus that supports data transfer rates up to 400Mbps (100/200/400 Mbps selectable)
and delivers more than 30 times the bandwidth of the popular USB periphera l standard.
H
HDC
Hard Disk Controller is a special-purpose chip and circuitry that directs an d controls reading from and writing
to a computer’s disk drive.
I
IDE
Integrated Device Electronics is a disk drive interface where the controller ele ctronics reside on the drive
itself. This allows elimination of the need for a separate adapter card.
IEEE
IEEE stands for Institute of Electrical and Electronics Engineers, pr onounced “I-triple-E.” Founded in 1963,
IEEE is an organization composed of engineers, scientists, and students. IEEE is best known for developing
standards for the computer and electronics industry.
I/O
I/O (Input/output). Two of the three activities that characterize a computer (input, processing, and output).
Refers to the complementary tasks of gathering data for the microprocess or to work with and making the
results available to the user through a device such as the displa y, disk drive, or printer.
IRQ
IRQ (Interrupt ReQuest). A method by which a device can request to be serviced by the device ’s software
driver. The system board uses a PIC to monitor the priority of the requests from all devices. When a r equest
occurs, a microprocessor suspends the current operation and gives c ontrol to the device driver associated
with the interrupt.
ISA
ISA (Industry Standard Architecture) is an 8-bit / 16-bit bus that provi des a buffered interface from devices on
expansion cards to the PC internal bus.
L
LAN
LAN (Local Area Network). A group of computers and other devices spanned over a relative ly limited area
(i.e. a single building).
LBA
LBA (Logical Block Address). A unit of data supplied or requested b y a host computer.
M
MIDI
MIDI (Musical Instrument Digital Interface). An industry-standard connection for computer control of musical
instruments and devices. A hardware and data standard for communicating between hardware. Most
